My 2008 is experiencing similar problems I have a squeak in the front end when going over bumps and with heaver bumps i can feel a metallic rub and along with the sound
the sound like a cheap bed spring and ride quality is bad it has been swaying and the front end has been vibration.
I have been to the dealer and they couldn't find anything wrong and since i have 56k on it would not been covered under warranty.
this week i plan to bring it to local specialist what I'm leaning is the upper strut mount/bearing
wonder if anybody else had similar issues .
